# Spanish-Guaraní Code-Switching in Social Media: A Dependency Parsing Study

Kellert, 2026, International Journal of Bilingualism — Linguistics

Patterns: [Distinctions](https://dsrpevidence.org/pattern/distinctions), [Systems](https://dsrpevidence.org/pattern/systems)

## In short

Bilingual speech is organized as a system with a dominant 'matrix' language governing overall structure, and the finding turns on a categorical distinction in where within the sentence a switch occurs -- core grammatical slots behave differently from clause-edge slots.

## What they found (results)

Dependency-parsing analysis of a Spanish-Guaraní social-media corpus found Guaraní functioned as the dominant matrix language overall, with switches into Spanish concentrated at core grammatical positions (subjects, objects, obliques) and switches into Guaraní concentrated at clause-edge/discourse positions.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
